Increased amygdala reactivity during processing of certain types emotional stimuli (e.g., fear, anger) has been observed in patients with anxiety disorders such as social phobia and posttraumatic stress disorder (PTSD). It is uncertain whether this heightened specific to treatment-seeking or a general feature individuals increased anxiety-related temperamental traits.Thirty-two physically healthy subjects 18-21 years old were recruited from large pool college students. Of these, 16 chosen on...
Marines who had first received Mindfulness-Based Mind Fitness Training, which can affect brain structures integral to the body’s response stress, experienced quicker heart rate and breathing recovery, improved sleep quality, lower levels of neuropeptide Y after stressful combat training than a comparison group without intervention.
Well-established in the field of bioelectronic medicine, Spinal Cord Stimulation (SCS) offers an implantable, non-pharmacologic treatment for patients with intractable chronic pain conditions. Chronic is a widely heterogenous syndrome regard to both pathophysiology and resultant phenotype. Despite advances our understanding SCS-mediated antinociception, there still exists limited evidence clarifying pathways recruited when patterned electric pulses are applied epidural space. The rapid...
<h3>Background</h3> Functional neuroimaging may elucidate the pathophysiologic features of anxiety disorders and site action anxiolytic drugs. A large body evidence suggests that amygdala associated limbic structures play a critical role in expression be treatment targets for <h3>Objective</h3> To determine whether lorazepam dose-dependently attenuates blood oxygenation level–dependent functional magnetic resonance imaging (BOLD fMRI) activation during an emotion face assessment task....
<h3>Context</h3> Chronic pain and depression are highly comorbid conditions, yet little is known about the neurobiological basis of processing in major depressive disorder (MDD). <h3>Objective</h3> To examine neural substrates underlying anticipation heat a group unmedicated young adults with current MDD. <h3>Design</h3> Functional magnetic resonance neuroimaging data were collected during an event-related factorial experimental paradigm. Painful nonpainful stimuli applied to left volar...
Liberals and conservatives exhibit different cognitive styles converging lines of evidence suggest that biology influences differences in their political attitudes beliefs. In particular, a recent study young adults suggests liberals have significantly brain structure, with showing increased gray matter volume the anterior cingulate cortex, amygdala. Here, we explore function by matching publicly-available voter records to 82 subjects who performed risk-taking task during functional imaging....
Understanding the neural substrates of anticipation is required for a comprehensive model ways in which anxiety influences information processing. While it apparent that insula and medial frontal cortex are involved processing physical (i.e., painful) stimuli, their role aversive affective stimuli has yet to be determined. Twenty-eight healthy non-phobic volunteers observed images (spiders snakes) were preceded by an auditory signal. The insula, dorsolateral prefrontal cortex,...
<h3>Context</h3>Posttraumatic stress disorder (PTSD) has been associated with executive or attentional dysfunction and problems in emotion processing. However, it is unclear whether these two domains of are related to common distinct neurophysiological substrates.<h3>Objective</h3>To examine the hypothesis that greater neuropsychological impairment PTSD relates disruption prefrontal-subcortical networks during emotional anticipation.<h3>Design</h3>Case-control, cross-sectional...
Recent studies suggest that altered function of higher-order appetitive neural circuitry may contribute to restricted eating in anorexia nervosa and overeating bulimia nervosa. This study used sweet tastes interrogate gustatory neurocircuitry involving the anterior insula related regions modulate sensory-interoceptive-reward signals response palatable foods.Participants who had recovered from were studied avoid confounding effects nutritional state. Functional MRI measured brain repeated...
